BOILER WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 327,136, datedSeptember 29,1885.

N0 model.)

To all whom it may concern:

Be it known that I, NEWTON W. CHAIN, of Columbia, in the county of Booneand State of Missouri, have invented certain new and usefulImprovements-in Boiler \Vashing-Ma chines; and I do hereby declare thefollowing to be a full, clear, and exact description ofthe invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompany ing drawing, whichforms part oft'his specification.

My invention relates to an improvement in boiler washing'machines; andit consists in a rotary shell or casing which has a number of perforatedtubes projecting inward toward its center, which tubes extend across theinner side of the cylinder in straight lines, so as to form projectionsto catch the clothes and carry them up and around as the cylinderrevolves,

as will be more fully described hereinafter, and particularly pointedout in the claim.

The accompanying drawing represents a vertical crosssection of a boilerembodying my invention.

A represents an ordinary wash-boiler, and B the revolving shell which isplaced therein. Projecting inward from the side of this shell toward thecenter are a suitable number of pipes, D, which are entirely separatefrom each other, and which are perforated at their sides and ends, so asto freely admit the water and steam. These pipes serve to raise theclothes from against the side of the boiler, so as to permit the steamto freely enter and pass up through the clothes while the water isboiling. These pipes also serve as a means upon which the clothes willcatch, so as to carry them up and around when the shell is made torevolve in either direction. Each pipe being separate and distinct, theends serve as a means upon which the clothes will catch, and thus becarried up to a greater heightthan where a mere ridge or rim is formedacross the boiler.

The cover-G is hinged to the shell in the usual manner, and is keptclosed by means of a spring catch. All around the top of the shell,where the cover is united to it, and around the lower edge of the coveritself, are formed the flanges I, which also serve to catch the clothesas the shell is made to revolve, and help to carry them up and around.These flanges, projecting inward, serve to contract the shell verymaterially at this point, and to such an extent that the clothes willlift in one mass or body. and carry them around until in nearly avertical position, when the weight of the clothes causes them to pullout and drop back into the water. These pipes and these flanges,cooperating together in this respect, cause a greater movementof theclothes inside of the shell than could be accomplished by either onealone. The more movement the clothes have the greater the friction amongthemselves, and the more freely the water passes through them.

Having thus described my invention, I claim- The revolving shellprovided with the flanges land a series of short pipes, D, which areperforated at their inner ends and sides, and which project toward thecenter of the shell, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
